簡(jiǎn)單C語言程序的例子

1、.例子：l #include main ()tips(); /*caller*/printf(“n Success is about banging on after others have let go”);tips() /*caller*/printf (“n When you reach the end of the rope tie a knot & hang on”,)0;上述程序的輸出結(jié)果如下：When you reach the end of the ropt tie a knot & hang on.Success is about hanging on after other

2、s have let go.l #include main()int a,fact;printf(“nEnter any number”);scanf(“%d”,&a);fact=rec(a);printf(“Factorial value is%d”,fact);rec(x);int x;int f;if(x=1)return(1);elsef=x*rec(x-1);return(f);其顯示的結(jié)果為： Factorial value is 2.l 比較兩個(gè)數(shù)較大的那個(gè)：#include main()int a,b,max;scanf (“%d%d”,&a,&b);if (ab)max=a;

3、else max=b;printf (“%d”,max);l 輸出a+b的值：#include void main()int a,b,x;scanf (“%d%d”,&a,&b);x=a+b;printf (“%d”,x);l 輸出a,b中最大的一位數(shù)：#include int max(int x,int y)int z;if (xy) z=x;else z=y;return(z);void main()int a,b,c;scanf (“%d%d”,&a,&b);c=max(a,b);printf (“%dn”,c);l 輸出Hello:#include int main()printf (

4、“Hello!”);return 0;l 求1100的和：#include int main()int s,n;s=0,n=1;A: s=s+n;n=n+1;if (n=100)goto A;printf (“%d”,s);l 請(qǐng)輸入一個(gè)三位數(shù)，將其各位逆序輸出：（如153，輸出351）#include void main()int x,y,a,b,c;printf (請(qǐng)輸入一個(gè)三位數(shù)的數(shù)：);scanf(%d,&x);a=x/100;b=x%100/10;c=x%10;y=c*100+b*10+a;printf (n%d,y);#include void main()int x,a,b,c,

5、d;printf (請(qǐng)輸入一個(gè)三位數(shù)的數(shù)：);scanf(%d,&x);a=x/100;b=x%100/10;c=x%10;d=c*100+b*10+a;printf (n%dn,d);買雞：#include void main()int x,y,z;if(x=0&x=0&y=0&z=100)while (x=19)x=0; 5*x+3*y+z/3=100&x+y+z=100;x=x+1;printf(%d%d%d,x,y,z);y=(100-5*x-z/3)/3&y=100-x-z;z=(100-5*x-3*y)*3&z=100-x-y;#include void main()int x=0

6、,y,z;while (x=19)5*x+3*y+z/3=100&x+y+z=100;x=x+1;printf(%d%d%d,x,y,z);#include void main()int x=0,y=0,z=0;while (x=19)while (y=33)while (z=100)z=(100-5*x-3*y)*3&z=100-x-y;z=z+1;printf(%dt,z);y=(100-5*x-z/3)/3&y=100-x-z;y=y+1;printf(%dt,y);x=x+1;printf(%dt,x);l 計(jì)算x=20+3(x-1):#include void main()int a

7、ge(int x)int i,j;scanf(“%d”,&i);j=age(i);printf(“age=%dn”,j);int age(int x)int z;if(x=1) z=20;else z=age(x-1)+3;return(z);l 編寫程序求圓柱體的表面積和體積：#include #define PI 3.14 /*定義PI為符號(hào)常量，值為3.14*/void main()float r,h,s,v;printf(“請(qǐng)輸入半徑r和高h(yuǎn)的值：n”);scanf(“%f%f”,&r,&h); /*輸入半徑r和高h(yuǎn)*/s=2*PI*r*h; /*計(jì)算圓柱體表面積*/v=PI*r*r*

8、h; /*計(jì)算圓柱體體積*/printf(“s=%f,v=%fn”,s,v);l 自增，自減運(yùn)算符的使用：#include void main()int i=5,j=5;int x,y;x=i+;y=+j;printf(“%dt%dn”,-x+,-(+y);printf(“%dt%dt%dt%dn”,i,j,x,y);l 自增、自減運(yùn)算符的基本運(yùn)算：#include void main()int k=4;int x,y,z;x=18-k+;printf(“x=%d”,x);printf(“k=%dn”,k);y=+k+6;printf(“y=%d”,y);printf(“k=%dn”,k);z

9、=+k+k+;printf(“z=%dn”,z);結(jié)果：x=14,k=5;y=12,k=6;z=14.l 輸出單個(gè)字符：#include void main()char a,b;a=o;b=k;putchar(a);putchar(b);putchar(n);l 輸入字符舉例：#include void main()char c;c=getchar(); /*從鍵盤讀入一個(gè)字符*/putchar(c);/*顯示輸入的字符*/猜數(shù)游戲：#include #include #include int main()int x,i=0,guess;srand(time(NULL);x=rand()%10

10、0+1;printf(請(qǐng)你猜數(shù)：);doscanf(%d,&guess);if(xguess)printf(你猜小了！n);elseprintf(你贏了！n);break;i+;if (i=10)printf(隨機(jī)數(shù)是：%dn,x);printf(你已經(jīng)猜 錯(cuò)了10次，我贏了，哈哈！n);break;printf(請(qǐng)你再猜：); while(1);#include void main()int a=2,*p=&a,*q=&a;Printf(%d,%dn,*p+,*(q+);P=&a;q=&;Printf (%d%dn,*p,(*q)+);Printf(%d%dn,*p,+(*q);結(jié)果為：2,2 2,2 4,4(從又向左算）#include Void main()Int a,b,c;Int *pa,*pb,*pc;Pa=&a;pb=&b;pc=&c;Scanf (%d%d,pa,pb);Printf (a=%d,b=%dn,*pa,*pb);C=a+b;Printf (c=%dn,*pc);*pc=a+*pb;Printf (c=%d從100到200之間有哪些數(shù)除4多2，除7多3，除9多5？#in
